AAP and BJP cadre clash after Kejriwal's detention and subsequent protests in Gujarat.

AAP leader Manish Sisodia today accused Gujarat Police of spying on him, a day after party leader Arvind Kejriwal was briefly "detained" in Gujarat while on a tour to "inspect" development in Narendra Modi's state.

Sisodia, who along with Kejriwal is on a four-day visit to Gujarat, alleged that police was troubling, questioning and threatening people he had met last evening.

Kejriwal had yesterday accused Modi of trying to stall his visit to Gujarat meant to "inspect" development.

After he embarked on his tour to "verify" Modi's claims of providing water, power, education and healthcare to people in Gujarat, the former Delhi Chief Minister was taken to Radhanpur police station in North Gujarat and allowed to leave after half an hour.

Gujarat state AAP convenor Sukhdev Patel had claimed that Kejriwal was detained, though the police denied it by saying that they had only "briefed" Kejriwal on the model code of conduct which came into force after declaration of the poll schedule.

However, Kejriwal alleged that the police had acted after "orders from the top".

"We came to know in the morning itself that all District Superintendents of Police (DSPs) were instructed to stop Kejriwal under any circumstances. Modi also sent some people with black flags. We knew that they would resort to such tactics," Kejriwal had said.
